I bought a PS4 from a buddy a year or two ago and kept it offline in anticipation for a hack. Because the system was already on a lower firmware than current at the time I didn't go online to add my PSN account, so I am currently using an offline profile with no ties to PSN. I earned some trophies playing Just Cause 3 which he had installed. I plan on modding this console and earning trophies with backup games. If this console ever goes online and my PSN profile added to the offline accout, would I transfer my trophies over to my PSN account. Offline Account > Go online and merge to PSN > Sync trophies. Would that work?
